measures signal strength and 3) a flashing red light.
Listen intently for the IMPULSE audio signal tone. The
tone increases in volume and raises in pitch when
directly over the target and decreases in volume
and lowers in pitch when moving away.
5. Overlap your sweeps by at least 50 percent.
Remember that your coil’s depth penetration is
conical, and if you don’t overlap each sweep you’ll
miss the deeper targets.
6. Search in a methodical manner. Pay close
attention to where you’re going and where you’ve
Be sure to keep the search
